SYMPTOMS

When you use a source code control tool such as Visual SourceSafe on a Visual Basic project, .frm files appear to lose font information for controls.

CAUSE

If a control's font matches the font of the parent form exactly, the font blocks are optimized out of the property definitions. When Visual Basic loads a control that does not contain a font block, the font property of the control is set to the font that is used by the control's parent form.

RESOLUTION

You can safely ignore a difference report that shows a missing font.

To avoid the problem, do one of the following:

  • Set the Font property of the Form to a font or font size that is not used by the controls on the form.
  • Set the Font property of each control at run time.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to reproduce behavior

  1. In Visual Basic, create a new Standard EXE project. Form1 is created by default.
  2. Add a CommandButton to Form1.
  3. Change the font of the CommandButton in the Properties window.
  4. Save the project and add the project to Visual SourceSafe.
  5. Check out Form1.
  6. Change the Font property of CommandButton1 to be the same as Form1.
  7. Save Form1 and close Visual Basic.
  8. Start Visual Basic and reload your project.
  9. Add a line of code to the project and delete it. This causes Visual Basic to mark the form as "dirty," which prompts cleanup when it is saved.
  10. Save Form1.frm.
  11. From the Tools menu, point to SourceSafe and click Show Differences to open the Difference Options dialog box. Click OK to display the difference report.
RESULT: The difference report shows that the reference to the Font property of Command1 was deleted.
